Air Permeability Tester ToniPERM II – Model 6575

Air permeability tester for the automatic determination of the specific surface (grinding fineness / Blaine value) of powdered materials, especially for the permanent control of manufacturing characteristics in the daily laboratory work.

 

Key benefits for the user:

✓ 5.7″ color display with touchscreen operation for intuitive and user-friendly operation
✓ Alternating operation with two measuring cells enables a higher test frequency
✓ Implication of the environmental temperature into the calculation of the specific surface
✓ Height adjustable optical sensors for the adaption of the cycle time to different types of material
✓ Calibration using reference materials feasible by the user
✓ Density, initial weight and porosity are freely selectable
✓ Integrated compartment for the storage of consumables and reference materials
✓ Any number of correction factors (K-factors) storable
✓ Runtime indication resolution: 0.1 seconds
✓ Calculation of the specific surface based on any number of single measurements on one powder bed
✓ Integrated data base for the storage of up to 300 test results including all test parameters
✓ Integrated data base for the storage of materials with different density and porosity
✓ Possibility to connect a printer for automatic raw data print out
✓ USB interface for easy and fast export of test results including all test parameters
✓ Possibility to connect a dial gauge for the automated compensation of compaction deviations
✓ Improved comparability of the test results by separately calibratable measuring cells (compensation of minimum volume differences of the measuring cells)
✓ Ability to change the correction factor subsequently for an extended result evaluation

Description

Operating Principle

Using the plunger the powder will be compacted within the permeability cell to a defined volume.

After the selection of the test material from the material data base and the entry of the test-specific parameters, the test is carried out fully automatically.

Via a U-tube manometer, which is equipped with adjust-able light barriers, a negative pressure is generated by means of a solenoid valve and a diaphragm pump. This negative pressure is compensated by an amount of air flowing through the powder bed in the measuring cell. Then the ToniPERM II automatically evaluates the test, displays the result and stores the result including the test parameters in the database.
